com.tangosol.config.expression (Java API Reference for Oracle® Coherence Community Edition)

Defines classes and interfaces for representing and evaluating expressions.

Since:: 12.1.2

Interface Summary
Interface	Description
Expression<T>	A `Expression` represents a calculation to be evaluated at runtime, during which, one or more `Parameter`s may be required.
ExpressionParser	An `ExpressionParser` parses a `String` representation of some calculation to produce an `Expression`, that of which when evaluated will return an expected type of value.
ParameterResolver	A `ParameterResolver` provides a mechanism resolve and lookup named `Parameter`s.

Class Summary
Class	Description
ChainedParameterResolver	A `ChainedParameterResolver` is a `ParameterResolver` that consults zero or more provided `ParameterResolver`s in the order in which they were defined or added to resolve a `Parameter`.
LiteralExpression<T>	A `LiteralExpression` is a literal (aka: constant) `Expression`.
NullParameterResolver	A `NullParameterResolver` is a `ParameterResolver` that always resolves named `Parameter`s to `null`.
Parameter	A `Parameter` represents an optionally named and optionally explicitly typed `Expression`.
PropertiesParameterResolver	A `PropertiesParameterResolver` is a `ParameterResolver` that is based on a `Properties` instance.
ScopedParameterResolver	A `ScopedParameterResolver` is a `ParameterResolver` implementation that provides the ability to "scope" `Parameter` definitions to either an inner (wrapped) or outer `ParameterResolver`, such that those being defined in the outer `ParameterResolver` hide those (of the same name) in the inner (wrapped) `ParameterResolver`.
SystemEnvironmentParameterResolver	A `SystemEnvironmentParameterResolver` is a `ParameterResolver` that is an environment getter for Coherence environment properties implemented using `System.getenv(String)`.
SystemPropertyParameterResolver	A `SystemPropertyParameterResolver` is a `ParameterResolver` that is based on property methods on `System`.
Value	A `Value` is an immutable object that represents a value whose type is unknown at compile time.
ValueMacroExpression	A `ValueMacroExpression` is a string value potentially containing expandable macros.
ValueMacroExpression.DefaultDelimiterExpansionProcessor	Process macro parameter default delimiter expansion.
ValueMacroExpression.MacroExpansionProcessor	A Macro Expansion Processor for a macro not containing any registered delimiters.
ValueMacroExpression.OffsetLengthSubstringExpansionProcessor	Process `:offset` and `:length substring expansion.`
ValueMacroExpression.SpaceDefaultDelimiterExpansionProcessor	`ValueMacroExpression.SpaceDefaultDelimiterExpansionProcessor` performs DefaultDelimiter expansion processing and disambiguates `: -` for offset and length from space for default delimiter.
