Interface Summary

Interface	Description
Arguments	This class Arguments represents the wrapped tokens that are tokenized and parsed arguments provided to the Executor.
Compiler	This Compiler interface provides a way to implement your own version of compiler for directive or recipe.
Directive	Directive is a user defined directive.
DirectiveAlias	This interface DirectiveAlias provides a way to check if a directive is aliased and if there it is aliased to what it is being aliased.
DirectiveContext	DirectiveContext provides the context object to the processing of directives.
DirectiveEnforcer	This class defines the interfaces that would provide the ability to check whether the user should be provided access to the directive being used.
Executor<I,O>	A interface defining the wrangle Executor in the wrangling RecipePipeline.
ExecutorContext	Pipeline Context for passing contextual information to the pipeline being executed.
GrammarMigrator	This is a interface for migrating grammar from one version to other.
RecipeParser	A specification for how RecipePipeline will process.
RecipePipeline<I,O,E>	RecipePipeline executes array of Executor in the order they are specified.
TransientStore	TransientStore is an interface that holds volatile information that's present across all the steps associated with the directives that are processing a single record.

Class Summary

Class	Description
CompileStatus	This class CompileStatus contains the status of compilation.
DirectiveConfig	This class DirectiveConfig defines the configuration for the Wrangler.
ErrorRecord	Specifies the structure for Error records.
ErrorRecordBase	Base class for error record that includes the critical fields.
LazyNumber	This class holds a number value that is lazily converted to a specific number type
Optional	This class Optional is a helper class used in specifying whether a argument for the directive is optional or not.
Pair<F,S>	A pair consisting of two elements - first & second.
RecipeSymbol	This object RecipeSymbol stores information about all the TokenGroup ( TokenGroup represents a collection of tokens generated from parsing a single directive).
RecipeSymbol.Builder	This inner class provides a builder pattern for building the RecipeSymbol object.
Row	Row defines the schema and data on which the wrangler will operate upon.
SourceInfo	Class description here.
SUID	This class SUID creates a unique 64-bit ID with capacity to generate around 64K unique ids within a millisecond.
TokenGroup	Class description here.
Triplet<F,S,T>	A triplet consisting of three elements - first, second & third.

Enum Summary

Enum	Description
ExecutorContext.Environment	Specifies the environment in which wrangler is running.
TransientVariableScope	TransientVariableScope defines the scope of the transient variable.

Exception Summary

Exception	Description
CompileException	This class CompileException is thrown when there is any issue with compiling the Recipe.
DirectiveExecutionException	A Executor specific exception used for communicating issues with execution of pipeline in that step.
DirectiveLoadException	Class description here.
DirectiveNotFoundException	Class description here.
DirectiveParseException	An exception thrown when there is error in parsing specification.
ErrorRowException	Exception throw when the record needs to emitted to error collector.
RecipeException	A RecipePipeline specific exception used for communicating issues with execution of pipeline.
ReportErrorAndProceed	Exception throw when the record needs to emitted to error collector.
