public EagerTagDecorator(T tag)

Method Detail

getTag

public T getTag()

interpret

public final String interpret(TagNode tagNode,
                              JinjavaInterpreter interpreter)

Specified by:

interpret in interface Tag

innerInterpret

protected String innerInterpret(TagNode tagNode,
                                JinjavaInterpreter interpreter)

getName

public String getName()

Specified by:

getName in interface Importable

getEndTagName

public String getEndTagName()

Specified by:

getEndTagName in interface Tag

Returns:

Get name of end tag (lowerCase). Null if it's a single tag without content.

isRenderedInValidationMode

public boolean isRenderedInValidationMode()

Specified by:

isRenderedInValidationMode in interface Tag

eagerInterpret

public String eagerInterpret(TagNode tagNode,
                             JinjavaInterpreter interpreter,
                             InterpretException e)

Return the string value of interpreting this tag node knowing that a deferred value has been encountered. The tag node can not simply get evaluated normally in this circumstance.

Parameters:

tagNode - TagNode to interpret.

interpreter - The JinjavaInterpreter.

e - The exception that required non-default interpretation. May be null

Returns:

The string result of performing an eager interpretation of the TagNode

buildToken

public TagToken buildToken(TagNode tagNode,
                           InterpretException e,
                           int deferredLineNumber,
                           int deferredPosition)

renderChildren

public String renderChildren(TagNode tagNode,
                             JinjavaInterpreter interpreter)

Render all children of this TagNode.

Parameters:

tagNode - TagNode to render the children of.

interpreter - The JinjavaInterpreter.

Returns:

the string output of this tag node's children.

getEagerImage

public final String getEagerImage(Token token,
                                  JinjavaInterpreter interpreter)

Casts token to TagToken if possible to get the eager image of the token.

Parameters:

token - Token to cast.

interpreter - The Jinjava interpreter.

Returns:

The image of the token which has been evaluated as much as possible.

See Also:

getEagerTagImage(TagToken, JinjavaInterpreter)

getEagerTagImage

public String getEagerTagImage(TagToken tagToken,
                               JinjavaInterpreter interpreter)

Uses the EagerExpressionResolver to partially evaluate any expression within the tagToken's helpers. If there are any macro functions that must be deferred, then their images are pre-pended to the result, which is the partial image of the TagToken.

Parameters:

tagToken - TagToken to get the eager image of.

interpreter - The Jinjava interpreter.

Returns:

A new image of the tagToken, which may have expressions that are further resolved than in the original Token.getImage().
