retraceVariable

public Object retraceVariable(String variable,
                              int lineNumber)

Resolve a variable from the interpreter context, returning null if not found. This method updates the template error accumulators when a variable is not found.

Parameters:

variable - name of variable in context

lineNumber - current line number, for error reporting

Returns:

resolved value for variable

resolveObject

public Object resolveObject(String variable,
                            int lineNumber)

Resolve a variable into an object value. If given a string literal (e.g. 'foo' or "foo"), this method returns the literal unquoted. If the variable is undefined in the context, this method returns the given variable string.

Parameters:

variable - name of variable in context

lineNumber - current line number, for error reporting

Returns:

resolved value for variable

resolveString

public String resolveString(String variable,
                            int lineNumber)

Resolve a variable into a string value. If given a string literal (e.g. 'foo' or "foo"), this method returns the literal unquoted. If the variable is undefined in the context, this method returns the given variable string.

Parameters:

variable - name of variable in context

lineNumber - current line number, for error reporting

Returns:

resolved value for variable

getContext

public Context getContext()

getResource

public String getResource(String resource)
                   throws IOException

Throws:

IOException

getConfig

public JinjavaConfig getConfig()

resolveELExpression

public Object resolveELExpression(String expression,
                                  int lineNumber)

Resolve expression against current context.

Parameters:

expression - Jinja expression.

lineNumber - Line number of expression.

Returns:

Value of expression.

resolveProperty

public Object resolveProperty(Object object,
                              String propertyName)

Resolve property of bean.

Parameters:

object - Bean.

propertyName - Name of property to resolve.

Returns:

Value of property.

resolveProperty

public Object resolveProperty(Object object,
                              List<String> propertyNames)

Resolve property of bean.

Parameters:

object - Bean.

propertyNames - Names of properties to resolve recursively.

Returns:

Value of property.
