Method Detail

getNodeType

public int getNodeType()
Description copied from class: ASTNode
Returns an integer value identifying the type of this concrete AST node. The values are small positive integers, suitable for use in switch statements.

For each concrete node type there is a unique node type constant (name and value). The unique node type constant for a concrete node type such as CastExpression is ASTNode.CAST_EXPRESSION.

Specified by:
getNodeType in class ASTNode
Returns:
one of the node type constants

subtreeMatch

public boolean subtreeMatch(ASTMatcher matcher,
                            Object other)
Description copied from class: ASTNode
Returns whether the subtree rooted at the given node matches the given other object as decided by the given matcher.

Specified by:
subtreeMatch in class ASTNode
Parameters:
matcher - the matcher
other - the other object, or null
Returns:
true if the subtree matches, or false if they do not match

getExpression

public Expression getExpression()
Returns the expression of this switch case, or null if there is none (the "default:" case).

Returns:
the expression node, or null if there is none

setExpression

public void setExpression(Expression expression)
Sets the expression of this switch case, or clears it (turns it into the "default:" case).

Parameters:
expression - the expression node, or null to turn it into the "default:" case
Throws:
IllegalArgumentException - if:
  • the node belongs to a different AST
  • the node already has a parent
  • a cycle in would be created

isDefault

public boolean isDefault()
Returns whether this switch case represents the "default:" case.

This convenience method is equivalent to getExpression() == null.

Returns:
true if this is the default switch case, and false if this is a non-default switch case
