Namespace ZptSharp.Expressions
Classes
AbortZptActionToken
An object which indicates that the current ZPT action should be cancelled/aborted.
AlphabeticValueGenerator
Implementation of IGetsAlphabeticValueForNumber which creates and returns alphabetic strings.
BuiltinContextsProvider
Provides the built-in contexts which are inherent to the TALES specification.
These are generally accessible as if they were root objects within a path expression.
If, for example, their names have been overwritten they may alternatively be referenced
explicitly with the CONTEXTS reserved variable name.
BuiltinContextsProviderFactory
Implementation of IGetsBuiltinContextsProvider which uses dependency injection to backfill the other dependencies, as well as the context & config. This may also return the contexts provider from RootContextsProvider if it is not-null.
ConfiguredDefaultExpressionTypeDecorator
Decorator for the IGetsExpressionType service. If the wrapped service does not produce a non-null result, then this decorator returns the DefaultExpressionType.
ContextAllVariablesAndValuesProvider
Implementation of IGetsAllVariablesFromContext which prefers definitions in the order:
DefinedVariablesOnlyTalesValueForExpressionContextAdapter
Implementation of IGetsNamedTalesValue which exposes defined (local & global) variables from the wrapped ExpressionContext.
ErrorHandlingContext
A model/contaier object which represents a context and additionally a handler which may be able to handle errors encountered during context processing.
ErrorHandlingResult
Gets the result of an attempt to handle an error.
EvaluationException
Exception raised when there is a problem evaluating an expression. See also: IEvaluatesExpression.
EvaluatorTypeRegistry
Implementation of IRegistersExpressionEvaluator which uses a in-memory dictionary to maintain registrations of evaluator types.
EvaluatorTypeResolver
Implementation of IGetsEvaluatorForExpressionType which uses a System.IServiceProvider to resolve expression evaluators.
ExpressionContext
An object which provides contextual values for the rendering of TALES expressions.
ExpressionContextExtensions
Extension methods for ExpressionContext.
ExpressionEvaluatorExtensions
Extension methods used with an IEvaluatesExpression.
ExpressionTypeProviderFactory
Default implementation of IGetsExpressionTypeProvider.
GlobalVariablesOnlyTalesValueForExpressionContextAdapter
Implementation of IGetsNamedTalesValue which exposes global variables from the wrapped ExpressionContext.
LocalVariablesOnlyTalesValueForExpressionContextAdapter
Implementation of IGetsNamedTalesValue which exposes local variables from the wrapped ExpressionContext.
NamedTalesValueForExpressionContextAdapter
A wrapper/adapter for an instance of ExpressionContext which allows it to be used as an instance of IGetsNamedTalesValue.
NoEvaluatorForExpressionTypeException
Raised when an implementation of IGetsEvaluatorForExpressionType cannot get an appropriate evaluator for an expression type.
PrefixExpressionTypeProvider
Implementation of IGetsExpressionType which reads the expression prefix. This class also implements IRemovesPrefixFromExpression.
RegistryBasedExpressionEvaluator
An implementation of IEvaluatesExpression which makes use of the registry pattern to select and delegate execution to another implementation (of the same interface). This selection occurs based upon the expression type.
Additionally, when delegating to an implementation of IEvaluatesExpression from the registry, any expression-type prefix upon the expression is removed before this delegation occurs.
RepetitionInfo
Provides contextual information about a repetition/iteration. This is used in looping constructs.
RomanNumeralGenerator
Implementation of IGetsRomanNumeralForNumber which generates roman numerals from integers.
RootContextConfigHelper
An implementation of IConfiguresRootContext which allows setting of global variables into an expression context.
StructuredMarkupObjectAdapter
An implementation of IGetsStructuredMarkup which wraps any object,
exposing its Object.ToString() method via GetMarkupAsync().
WellKnownExpressionPrefix
A container for runtime constants representing the built-in types of TALES expression.
Structs
GetValueResult
Represents the outcome of TryGetValueAsync(String, CancellationToken)
Interfaces
IEvaluatesExpression
An object which evaluates and returns the result of a TALES expression. This is the core interface for an "expression evaluator".
IGetsAllVariablesFromContext
An object which can get all of the variable definitions and their corresponding values from an ExpressionContext.
IGetsAlphabeticValueForNumber
An object which can get an alphabetic reference for a specified non-negative integer.
IGetsBuiltinContextsProvider
An object which gets an instance of BuiltinContextsProvider for a specified expression context and rendering configuration.
IGetsDictionaryOfNamedTalesValues
A specialisation of IGetsNamedTalesValue which can provide a dictionary of many named TALES values.
IGetsEvaluatorForExpressionType
An object which chooses a strategy (an appropriate implementation of IEvaluatesExpression) for a specified expression type.
IGetsExpressionType
An object which can determine the string identifier which indicates an expression type. This is typically a prefix to the expression body.
IGetsExpressionTypeProvider
An object which may be used as a factory for instances of IGetsExpressionType.
IGetsNamedTalesValue
An object which provides its own logic for getting named values when resolving a TALES expression.
IGetsRomanNumeralForNumber
An object which will get the roman numereral version of a specified non-zero, non-negative number. Roman numerals are generated and returned in uppercase, using the English/Latin alphabet (invariant culture).
IRegistersExpressionEvaluator
An object which is used to register implementations of IEvaluatesExpression to be used for specific expression types.
IRemovesPrefixFromExpression
An object which can get a version of a TALES expression where its expression-type prefix (if any) has been removed.
