The type of the input field can be any subclass of \*(CbSoMField\f1, and the type of the output is the corresponding subclass of \*(CbSoSField\f1. \&For example, if the input type is \*(CbSoMFVec3f\f1, the output type will be \*(CbSoSFVec3f\f1. The type is specified when an instance of the class is created. For example, \*(CbSoSelectOne(SoMFFloat::getClassTypeId())\f1 creates an engine that selects one floating-point value. .sp Note \&that unlike most other engine fields, the \*(Cbinput\f1 field and \*(Cboutput\f1 are pointers. Note also that by default \*(Cbinput\f1 does not contain any values, and no value is output from the engine. .SH INPUTS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(CrSoSFInt32 .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(Cbindex .br .in 1i \f1Index of the value to select from the multiple-value field. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(Cbinput .br .in 1i \f1The multiple-value field from which the value will be selected. .sp .in 0.5i .SH OUTPUTS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr() .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(Cboutput\*(Cr .br .in 1i \f1The single value selected. .sp .in 0.5i .SH METHODS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbSoSelectOne\*(Cr(SoType inputType) .br .in 1i \f1Constructor.
