Parser

public Parser(Reader reader)

Create a Parser reading JSLT source from the given Reader. Uses a ClasspathResourceResolver for import statements.

Method Details

compile

public static Expression compile(File jslt)

Compile the given JSLT file.

compile

public static Expression compile(File jslt,
 Collection<Function> functions)

Compile the given JSLT file with the given predefined functions.

compileString

public static Expression compileString(String jslt)

Compile JSLT expression given as an inline string.

compileString

public static Expression compileString(String jslt,
 Collection<Function> functions)

Compile JSLT expression given as an inline string with the given extension functions.

compileResource

public static Expression compileResource(String jslt)

Load and compile JSLT expression from the classpath.

compileResource

public static Expression compileResource(String jslt,
 Collection<Function> functions)

Load and compile JSLT expression from the classpath with the given extension functions.

compile

public static Expression compile(String source,
 Reader reader,
 Collection<Function> functions)

Compile JSLT expression from the Reader. The source is just a name used in error messages, and has no practical effect.

withSource

public Parser withSource(String thisSource)

Create a new Parser with the given source name. The name is a string used in error messages.

withFunctions

public Parser withFunctions(Collection<Function> theseFunctions)

Create a new Parser with the given extension functions.

withResourceResolver

public Parser withResourceResolver(ResourceResolver thisResolver)

Create a new Parser with the given resource resolver.

withNamedModules

public Parser withNamedModules(Map<String,Module> thisModules)

Create a new Parser with the given modules registered. The keys in the map are the module "names", and importing these names will bind a prefix to the modules in this map. The names can follow any syntax.

withObjectFilter

public Parser withObjectFilter(String filter)

Create a new Parser with the given filter for object values. For all key/value pairs in objects being created, if this filter returns false when given the value, the key/value pair is omitted.

withObjectFilter

public Parser withObjectFilter(JsonFilter filter)

Create a new Parser with the given filter for object values. For all key/value pairs in objects being created, if this filter returns false when given the value, the key/value pair is omitted.

compile

public Expression compile()

Compile the JSLT from the defined parameters.
