findChildrenWithType

public static List<org.antlr.runtime.tree.CommonTree> findChildrenWithType(org.antlr.runtime.tree.CommonTree tree,
 int type)

Find all children with the given type in the provided tree. Will only check 1st level children (i.e., this method is not recursive.)

Parameters:

tree -

type -

Returns:

all children found with the given token type

findChildrenWithType

public static List<org.antlr.runtime.tree.CommonTree> findChildrenWithType(org.antlr.runtime.tree.CommonTree tree,
 AntlrTokens tokens,
 String typeName)

Find all children with the given type in the provided tree. Will only check 1st level children (i.e., this method is not recursive.)

Parameters:

tree -

tokens -

typeName -

Returns:

all children found with the given token type

findAllChildrenWithType

public static List<org.antlr.runtime.tree.CommonTree> findAllChildrenWithType(org.antlr.runtime.tree.CommonTree tree,
 int type)

Parameters:

tree -

type -

Returns:

the list of children found with the given type

findAllChildrenWithType

public static List<org.antlr.runtime.tree.CommonTree> findAllChildrenWithType(org.antlr.runtime.tree.CommonTree tree,

Parameters:

tree -

tokens -

typeName -

Returns:

the list of children found with the given type

findAllChildrenWithType

public static List<org.antlr.runtime.tree.CommonTree> findAllChildrenWithType(org.antlr.runtime.tree.CommonTree tree,

Parameters:

tree -

tokens -

typeName -

Returns:

the list of children found with the given type
