JspAttribute

JspAttribute(Node.NamedAttribute na,
 boolean dyn)

Use this constructor if the JspAttribute represents a named attribute. In this case, we have to store the nodes of the body of the attribute.

Method Details

getName

public String getName()

Returns:

The name of the attribute

getLocalName

public String getLocalName()

Returns:

The local name of the attribute

getURI

public String getURI()

Returns:

The namespace of the attribute, or null if in the default namespace

getValue

public String getValue()

Only makes sense if namedAttribute is false.

Returns:

the value for the attribute, or the expression string (stripped of "invalid input: '<'%=", "%>", "%=", or "%" but containing "${" and "}" for EL expressions)

setValue

public void setValue(String val)

getNamedAttributeNode

public Node.NamedAttribute getNamedAttributeNode()

Only makes sense if namedAttribute is true.

Returns:

the nodes that evaluate to the body of this attribute.

isExpression

public boolean isExpression()

Returns:

true if the value represents a traditional rtexprvalue

isNamedAttribute

public boolean isNamedAttribute()

Returns:

true if the value represents a NamedAttribute value.

isELInterpreterInput

public boolean isELInterpreterInput()

Returns:

true if the value represents an expression that should be fed to the expression interpreter

isLiteral

public boolean isLiteral()

Returns:

true if the value is a string literal known at translation time.

isDynamic

public boolean isDynamic()

XXX

getEL

public ELNode.Nodes getEL()

getExpectedType

public String getExpectedType()

getExpectedReturnType

public String getExpectedReturnType()

getExpectedParamTypes

public String[] getExpectedParamTypes()
