get()

List< ReturnType > get	(	const UPtrList< T > &	list,
		const AccessOp &	aop
	)

List of values generated by applying the access operation to each list item.

For example,

PtrListOps::get(mesh.boundaryMesh(), nameOp<polyPatch>());

names() [1/2]

List< word > names	(	const UPtrList< T > &	list,
		const UnaryMatchPredicate &	matcher
	)

List of names generated by calling name() for each list item and filtered for matches

For example,

wordRes matches(...);
PtrListOps::names(mesh.boundaryMesh(), matches);
 
PtrListOps::names(mesh.boundaryMesh(), predicates::always());

Here is the caller graph for this function:

names() [2/2]

List< word > names

(

const UPtrList< T > &

list

)

List of names generated by calling name() for each list item no filtering (ie, predicates::always)

firstMatching()

label firstMatching	(	const UPtrList< T > &	list,
		const UnaryMatchPredicate &	matcher
	)

Find first list item with 'name()' that matches, -1 on failure.

Referenced by coordinateSystems::cfind(), faBoundaryMesh::findIndex(), polyBoundaryMesh::findIndex(), coordinateSystems::findIndex(), faBoundaryMesh::findPatchID(), polyBoundaryMesh::findPatchID(), faBoundaryMesh::indices(), and polyBoundaryMesh::indices().

Here is the caller graph for this function:

findMatching()

labelList findMatching	(	const UPtrList< T > &	list,
		const UnaryMatchPredicate &	matcher
	)

Extract list indices for all items with 'name()' that matches.

Referenced by coordinateSystems::indices(), faBoundaryMesh::indices(), and polyBoundaryMesh::indices().
