Classes

AttributeDefinition

Model for an attribute definition, as would be used by a TAL 'attributes' attribute.

AttributeDefinitionsProvider

Implementation of IGetsAttributeDefinitions which parses and returns a collection of AttributeDefinition from an 'attributes' attribute value.

AttributesAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'attributes' attributes.

ConditionAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'condition' attributes.

ContentOrReplaceAttributeDecorator

Implementation of IHandlesProcessingError which handles both TAL 'content' or TAL 'replace' attributes. Their functionality is somewhat similar, and they cannot coexist on the same DOM node.

DefineAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'define' attributes.

DomExpressionEvaluator

Implementation of IEvaluatesDomValueExpression which evaluates DOM expressions returning an object that contains a list of nodes and supplemental information.

DomValueExpressionResult

Represents the result retrieved from IEvaluatesDomValueExpression.

InvalidTalAttributeException

Thrown when a TAL attribute value is improperly-formed or otherwise invalid.

NoOpTalContextProcessor

A IProcessesExpressionContext which performs no TAL-related activity. This is used at the centre of the decorator stack. If no particular TAL attributes are found then an empty processing result is returned.

OmitTagAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'omit-tag' attributes.

OnErrorAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'on-error' attributes.

This decorator is a little unusual (compared to the others) in that it really just puts a try/catch around whatever it wraps. If there is an error and there is a TAL on-error attribute present upon the node then this decorator will handle the error and prevent the error from halting the whole rendering process.

OnErrorExceptionAdapter

A wrapper/adapter class for instances of System.Exception which are added to the expression context by an OnErrorAttributeDecorator. This exposes a standard API, which is part of the TAL spec.

OnErrorHandlingException

Raised when a TAL on-error attribute encounters an exception whilst attempting to handle a different rendering exception.

In this case, the System.Exception.InnerException will relate to the error encountered during the on-error handling process. The OriginalException is the error (raised in a different part of the rendering process) which the on-error attribute was attempting to handle.

RecordMetalMacroNameDecorator

A decorator for IHandlesProcessingError which detects METAL define-macro attributes and adds a TALES local variable indicating the name of that macro. This is recorded as the macroname variable.

RepeatAttributeDecorator

Decorator for IHandlesProcessingError which handles TAL 'repeat' attributes.

RepetitionContextProvider

Implementation of IGetsRepetitionContexts which gets and prepares the repetition contexts.

TalAttributeSpecProvider

Implementation of IGetsTalAttributeSpecs which gets attribute specifications for the TAL attributes.

TalContextProcessorFactory

Implementation of IGetsTalContextProcessor which returns a context processor suitable for processing the TAL model-binding syntax.

TalExpressionEvaluationException

Thrown when a TAL attribute operation fails due to a error when evaluating a value expression.

TalExpressionResultInterpreter

Implementation of IInterpretsExpressionResult which provides interpretations of expression results, following the rules of TAL.

VariableDefinition

Model type representing a single TAL variable definition.

VariableDefinitionProvider

Implementation of IGetsVariableDefinitionsFromAttributeValue which parses and returns information about variable definitions from a TAL 'define' attribute value.

Interfaces

IEvaluatesDomValueExpression

An object which evaluates an expression and returns a value which may be used by the DOM.

IGetsAttributeDefinitions

An object which can provide a collection of AttributeDefinition from a string value. That string is expected to be in the format of a TAL 'attributes' attribute value.

IGetsRepetitionContexts

An object used by RepeatAttributeDecorator which gets the collection of ExpressionContext which are exposed by a specified expression result.

IGetsTalAttributeSpecs

An object which gets AttributeSpec instances for well-known TAL attributes.

IGetsTalContextProcessor

An object which can get a IHandlesProcessingError suitable for the TAL document-manipulation process.

IGetsVariableDefinitionsFromAttributeValue

An object which parses an attribute value and returns a collection of variable definitions.

IInterpretsExpressionResult

An object which interprets the result of a TALES expression, for the purposes of TAL.
