构造器详细资料

MemberAccess

public MemberAccess(Expression object,
                    boolean optional,
                    Span name,
                    boolean whole)

方法详细资料

isWhole

public boolean isWhole()

getObject

public Expression getObject()

Returns the object on which to access the member.

getName

public Span getName()

The name of the member.

getCachedMember

public Field getCachedMember()

Returns the cached member descriptor as returned by AbstractReflection.getField(Object, String) or

setCachedMember

public void setCachedMember(Field cachedMember)

Sets the member descriptor as returned by AbstractReflection.getField(Object, String) or AbstractReflection.getMethod(Object, String, Object...) for faster member lookups. Called by AstInterpreter the first time this node is evaluated. Subsequent evaluations can use the cached descriptor, avoiding a costly reflective lookup.

isOptional

public boolean isOptional()

evaluate

public Object evaluate(MagicScriptContext context,
                       Scope scope)

指定者:

evaluate 在类中 Node

setValue

public void setValue(MagicScriptContext context,
                     Scope scope,
                     Object value)

指定者:

setValue 在接口中 VariableSetter
