Constructor and Description
DslComponent(DslComponent.Scope scope) Resolve in scope relative to the current BrooklynTaskTags#getTargetOrContextEntity) target or context entity (where the scope defines an unambiguous relationship that will resolve to a single component - e.g.
DslComponent(DslComponent.Scope scope, DeferredSupplier<?> componentIdSupplier)
DslComponent(DslComponent.Scope scope, java.lang.String componentId) Resolve componentId in scope relative to the current BrooklynTaskTags#getTargetOrContextEntity) target or context entity.
DslComponent(DslComponent scopeComponent, DslComponent.Scope scope) Resolve in scope relative to scopeComponent entity (where the scope defines an unambiguous relationship that will resolve to a single component - e.g.
DslComponent(DslComponent scopeComponent, DslComponent.Scope scope, DeferredSupplier<?> componentIdSupplier) Resolve componentId in scope relative to scopeComponent.
DslComponent(DslComponent scopeComponent, DslComponent.Scope scope, java.lang.String componentId) Resolve componentId in scope relative to scopeComponent.
DslComponent(java.lang.String componentId) Deprecated. since 0.10.0; pass the DslComponent.Scope explicitly.

Constructor Detail

DslComponent

@Deprecated
public DslComponent(java.lang.String componentId)

Deprecated. since 0.10.0; pass the DslComponent.Scope explicitly.

Resolve componentId in the DslComponent.Scope.GLOBAL scope.

DslComponent

public DslComponent(DslComponent.Scope scope)

Resolve in scope relative to the current BrooklynTaskTags#getTargetOrContextEntity) target or context entity (where the scope defines an unambiguous relationship that will resolve to a single component - e.g. "parent").

DslComponent

public DslComponent(DslComponent scopeComponent,
                    DslComponent.Scope scope)

Resolve in scope relative to scopeComponent entity (where the scope defines an unambiguous relationship that will resolve to a single component - e.g. "parent").

DslComponent

public DslComponent(DslComponent.Scope scope,
                    java.lang.String componentId)

Resolve componentId in scope relative to the current BrooklynTaskTags#getTargetOrContextEntity) target or context entity.

DslComponent

public DslComponent(DslComponent.Scope scope,
                    DeferredSupplier<?> componentIdSupplier)

DslComponent

public DslComponent(DslComponent scopeComponent,
                    DslComponent.Scope scope,
                    java.lang.String componentId)

Resolve componentId in scope relative to scopeComponent.

DslComponent

public DslComponent(DslComponent scopeComponent,
                    DslComponent.Scope scope,
                    DeferredSupplier<?> componentIdSupplier)

Method Detail

newInstance

public static DslComponent newInstance(DslComponent scopeComponent,

                                       java.lang.Object componentId)

Checks the type of componentId to create the right kind of DslComponent (based on whether the componentId is already resolved. Accepts either a String or a DeferredSupplier.

newInstance

public static DslComponent newInstance(DslComponent.Scope scope,
