Method Detail

toExpr

public Expr toExpr()

isConstantTrue

public boolean isConstantTrue()

Description copied from class: Expr

is this expression the boolean literal value true?

Overrides:

isConstantTrue in class Expr

isConstantFalse

public boolean isConstantFalse()

Description copied from class: Expr

is this expression the boolean literal value false?

Overrides:

isConstantFalse in class Expr

getStringValue

public java.lang.String getStringValue()

Description copied from class: LiteralExpr

Return a string representing the Literal expr, NOT to be used for unparsing purposes, but rather the string that would be returned by the String.valueOf(char) method.

Specified by:

getStringValue in class LiteralExpr

walkFlow

public void walkFlow(org.aspectj.compiler.base.FlowCheckerPass w)

Overrides:

walkFlow in class ASTObject

cgTest

protected void cgTest(org.aspectj.compiler.base.bcg.CodeBuilder cb,
                      org.aspectj.compiler.base.bcg.Label tdest,
                      org.aspectj.compiler.base.bcg.Label fdest)

Description copied from class: Expr

Evaluates the expression in a context where its value will only be used to branch (from IfStmt, TriTestExpr, WhileStmt, DoStmt, and ForStmt). The expression, of course, will have boolean type. By default, this evaluates the expression to the stack and then emits an EQ/NE branch bytecode, but many expressions such as tests in BinopExpr will be able to do much better. May self-call Expr.cgValue(CodeBuilder).

Overrides:

cgTest in class Expr

cgValue

protected void cgValue(org.aspectj.compiler.base.bcg.CodeBuilder cb)

Description copied from class: Expr

Leaves the value of this expression on the stack. May self-call Expr.cgTest(CodeBuilder, Label, Label).

Overrides:

cgValue in class Expr

addConstant

public void addConstant(org.aspectj.compiler.base.bcg.FieldBuilder fb)

Specified by:

addConstant in class LiteralExpr

getBooleanValue

public boolean getBooleanValue()

Overrides:

getBooleanValue in class LiteralExpr

setBooleanValue

public void setBooleanValue(boolean _booleanValue)

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class LiteralExpr
