Field Details

extensions

private Collection<Function> extensions

functions

private Map<String,Function> functions

source

private String source

What file/resource are we parsing? Can be null, in cases where we don't have this information.

modules

private Map<String,Module> modules

Imported modules listed under their prefixes. This is scoped per source file, since each has a different name-module mapping.

files

private List<JstlFile> files

Tracks all loaded JSLT files. Shared between all contexts.

funcalls

private Collection<FunctionExpression> funcalls

Function expressions, used for delayed name-to-function resolution.

parent

private ParseContext parent

resolver

private ResourceResolver resolver

namedModules

private Map<String,Module> namedModules

Named modules listed under their identifiers.

preparationContext

private PreparationContext preparationContext

Variable declaration and usage tracking.

objectFilter

private JsonFilter objectFilter

Filter used to determine what object key/value pairs to keep.
