UnaryExpression

public UnaryExpression(Expression expression,
                       int operator)

方法详细信息

analyseCode

public FlowInfo analyseCode(BlockScope currentScope,
                            FlowContext flowContext,
                            FlowInfo flowInfo)

覆盖：

类 Expression 中的 analyseCode

optimizedBooleanConstant

public Constant optimizedBooleanConstant()

从类 Expression 复制的描述

Constant usable for bytecode pattern optimizations, but cannot be inlined since it is not strictly equivalent to the definition of constant expressions. In particular, some side-effects may be required to occur (only the end value is known).

覆盖：

类 Expression 中的 optimizedBooleanConstant

返回：

Constant known to be of boolean type

generateCode

public void generateCode(BlockScope currentScope,
                         CodeStream codeStream,
                         boolean valueRequired)

Code generation for an unary operation

覆盖：

类 Expression 中的 generateCode

参数：

currentScope - org.eclipse.jdt.internal.compiler.lookup.BlockScope

codeStream - org.eclipse.jdt.internal.compiler.codegen.CodeStream

valueRequired - boolean

generateOptimizedBoolean

public void generateOptimizedBoolean(BlockScope currentScope,
                                     CodeStream codeStream,
                                     BranchLabel trueLabel,

resolveType

public TypeBinding resolveType(BlockScope scope)

从类 Expression 复制的描述

Resolve the type of this expression in the context of a blockScope

覆盖：

返回：

Return the actual type of this expression after resolution

traverse

public void traverse(ASTVisitor visitor,
                     BlockScope blockScope)
