int globus_rsl_is_relation (globus_rsl_t *ast)
Detailed Description¶
The functions in this group return boolean values indicating whether an RSL syntax tree is of a particular type.Function Documentation¶
int globus_rsl_is_boolean (globus_rsl_t *ast)¶
RSL boolean test. The globus_rsl_is_boolean() function tests whether the the RSL pointed to by the ast parameter is a boolean composition of other RSL parse trees. The syntactically understood boolean compositions are '&' (conjunction), '|' (disjunction), and '+' (multi-request). Some bexamples of RSL booleans are1 & ( "queue" = "debug") ( "max_time" = "10000") 2 | ("count" = "1")("count" = "10") 3 + ( &("executable" = "1.exe") ) ( & ("executable" = "2.exe" )Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is a boolean
composition; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_boolean_and (globus_rsl_t *ast)¶
RSL boolean and test. The globus_rsl_is_boolean_and() function tests whether the the RSL pointed to by the ast parameter is a boolean 'and' composition of RSL trees. An example of a boolean and relation is1 & ( "queue" = "debug" ) ( "executable" = "a.out" )Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean_and() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is a boolean and of
RSL parse trees; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_boolean_multi (globus_rsl_t *ast)¶
RSL boolean multi test. The globus_rsl_is_boolean_multi() function tests whether the the RSL pointed to by the ast parameter is a boolean 'multi-request' composition of RSL trees. An example of a boolean multie-request relation is1 + ( &( "executable" = "exe.1") ( "count" = "2" ) ) 2 ( &( "executable" =" exe.2") ( "count" = "2" ) )Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean_multi() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is a boolean
multi-request of RSL parse trees; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_boolean_or (globus_rsl_t *ast)¶
RSL boolean or test. The globus_rsl_is_boolean_or() function tests whether the the RSL pointed to by the ast parameter is a boolean 'or' composition of RSL trees. An example of a boolean or relation is1 | ( "count" = "2" ) ( "count" = "4" )Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_boolean_or() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is a boolean and of
RSL parse trees; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_relation (globus_rsl_t *ast)¶
RSL relation test. The globus_rsl_is_relation() function tests whether the the RSL pointed to by the ast parameter is a relation. The RSL syntax supports the following relation operations:- =
- Equal
- !=
- Not Equal
- >
- Greater Than
- >=
- Greater Than or Equal
- <
- Less Than
- <=
- Less Than or Equal
- <=
- Less Than or Equal
1 "queue" = "debug" 2 "queue" != "slow" 3 "min_memory" > "1000" 4 "max_wall_time" >= "60" 5 "count < "10" 6 "host_count" <= "5"Note:
GRAM only supports equality relations.
Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is a relation;
otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_relation_attribute_equal (globus_rsl_t *ast, char *attribute)¶
RSL attribute name test. The globus_rsl_is_relation_attribute_equal() function tests whether the the RSL pointed to by the ast parameter is a relation with the attribute name which matches the string pointed to by the attribute parameter. This attribute name comparision is case-insensitive. Parameters:ast Pointer to an RSL parse tree structure.
attribute Name of the attribute to test
Returns:
The globus_rsl_is_relation_attribute_equal()
function returns GLOBUS_TRUE if the RSL parse tree pointed to by ast is
a relation and its attribute name matches the attribute parameter;
otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_relation_eq (globus_rsl_t *ast)¶
RSL equality operation test. The globus_rsl_is_relation_eq() function tests whether the the RSL pointed to by the ast parameter is an equality relation. An example of an equality relation is1 "queue" = "debug"Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation_eq() function returns
GLOBUS_TRUE if the RSL parse tree pointed to by ast is an equality
relation; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_is_relation_lessthan (globus_rsl_t *ast)¶
RSL less than operation test. The globus_rsl_is_relation_lessthan() function tests whether the the RSL pointed to by the ast parameter is a less-than relation. An example of a less-than relation is1 "count" = "10"Parameters:
ast Pointer to an RSL parse tree structure.
Returns:
The globus_rsl_is_relation_lessthan() function
returns GLOBUS_TRUE if the RSL parse tree pointed to by ast is a
less-than relation; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_value_is_concatenation (globus_rsl_value_t *ast)¶
RSL value concatenation test. The globus_rsl_value_is_concatenation() function tests whether the the RSL value pointed to by the ast parameter is a concatenation of RSL values. An example of an RSL value concatenation is1 $( "GLOBUSRUN_GASS_URL" ) # "/input"Parameters:
ast Pointer to an RSL value structure.
Returns:
The globus_rsl_value_is_concatenation() function
returns GLOBUS_TRUE if the RSL value pointed to by ast is a value
concatenation; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_value_is_literal (globus_rsl_value_t *ast)¶
RSL literal string test. The globus_rsl_value_is_literal() function tests whether the the RSL value pointed to by the ast parameter is a literal string value. An example of a literal string is1 "count"Parameters:
ast Pointer to an RSL value structure.
Returns:
The globus_rsl_value_is_literal() function returns
GLOBUS_TRUE if the RSL value pointed to by ast is a literal string
value; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_value_is_sequence (globus_rsl_value_t *ast)¶
RSL value sequence test. The globus_rsl_value_is_sequence() function tests whether the the RSL value pointed to by the ast parameter is a sequence of RSL values. An example of a sequence of values is1 "1" "2" "3"Parameters:
ast Pointer to an RSL value structure.
Returns:
The globus_rsl_value_is_sequence() function
returns GLOBUS_TRUE if the RSL value pointed to by ast is a value
sequnce; otherwise, it returns GLOBUS_FALSE.
int globus_rsl_value_is_variable (globus_rsl_value_t *ast)¶
RSL value variable test. The globus_rsl_value_is_variable() function tests whether the the RSL value pointed to by the ast parameter is a variable reference. RSL values. An example of a variable reference is1 $( "GLOBUSRUN_GASS_URL" )Parameters:
ast Pointer to an RSL value structure.
Returns:
The globus_rsl_value_is_sequence() function
returns GLOBUS_TRUE if the RSL value pointed to by ast is a value
sequnce; otherwise, it returns GLOBUS_FALSE.
