public final class ASTCharLiteral extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode> implements ASTLiteral
Represents a character literal.getConstValue()
allows to retrieve the actual runtime value. UsegetLiteralText()
to retrieve the text.

-
getConstValue
public @NonNull Character getConstValue()
Gets the char value of this literal.- Specified by:
getConstValue
in interfaceASTExpression
- Specified by:
getConstValue
in interfaceASTMemberValue
-
getLiteralText
public Chars getLiteralText()
Description copied from interface:ASTLiteral
Return the text of the literal in the source file. Note thatTextAvailableNode.getText()
may include parentheses.- Specified by:
getLiteralText
in interfaceASTLiteral
-
jjtClose
public void jjtClose()
-
getText
@NoAttribute public final Chars getText()
-
isCompileTimeConstant
public boolean isCompileTimeConstant()
Description copied from interface:ASTExpression
Returns true if this expression is a compile-time constant, and is inlined.
-
getParenthesisDepth
public int getParenthesisDepth()
Description copied from interface:ASTExpression
Returns the number of parenthesis levels around this expression. If this method returns 0, then no parentheses are present.E.g. the expression
(a + b)
is parsed as an AdditiveExpression whose parenthesisDepth is 1, and in((a + b))
it's 2.This is to avoid the parentheses interfering with analysis. Parentheses already influence parsing by breaking the natural precedence of operators. It would mostly hide false positives to make a ParenthesizedExpr node, because it would make semantically equivalent nodes have a very different representation.
On the other hand, when a rule explicitly cares about parentheses, then this attribute may be used to find out whether parentheses were mentioned, so no information is lost.

in interfaceASTExpression

buildConstValue
protected @Nullable Object buildConstValue()
-
getTypeMirror
public @NonNull JTypeMirror getTypeMirror()
Description copied from interface:TypeNode
Returns the compile-time type of this node. For example, for a string literal, returns the type mirror forString
, for a method call, returns the return type of the call, etc.This method ignores conversions applied to the value of the node because of its context. For example, in
1 + ""
, the numeric literal will have typeint
, but it is converted toString
by the surrounding concatenation expression. Similarly, inCollections.singletonList(1)
, theASTNumericLiteral
node has typeint
, but the type of the method formal isInteger
, and boxing is applied at runtime. Possibly, an API will be added to expose this information.- Specified by:
getTypeMirror
in interfaceTypeNode
- Returns:
- The type mirror. Never returns null; if the type is unresolved, returns
TypeSystem.UNKNOWN
.
