Method Detail

putOperation

void putOperation(Class<?> type)
                  throws OperationException

Registers an operation given its class. The operation class MUST be annotated using Operation annotation. If an operation having the same ID exists an exception will be thrown.

Throws:

OperationException

putOperation

void putOperation(Class<?> type,
                boolean replace)
                  throws OperationException

Registers an operation given its class. The operation class MUST be annotated using Operation annotation. If the replace argument is true then any existing operation having the same ID will replaced with this one.

Throws:

OperationException

putOperation

void putOperation(Class<?> type,
                boolean replace,
                String contributingComponent)
                  throws OperationException

Registers an operation given its class. The operation class MUST be annotated using Operation annotation. If the replace argument is true then any existing operation having the same ID will replaced with this one. Third argument represents the name of the component registring the operation

Throws:

OperationException

putOperation

void putOperation(OperationType op,
                boolean replace)
                  throws OperationException

Registers an operation given it's type.

Throws:

OperationException

Since:

5.9.2

removeOperation

void removeOperation(Class<?> key)

Removes an operation given its class. If the operation was not registered does nothing.

removeOperation

void removeOperation(OperationType type)

Removes an operation given it's type. If the operation was not registered does nothing.

Since:

5.9.2

getOperations

OperationType[] getOperations()

Gets all operation types that was registered.

getOperation

OperationType getOperation(String id)
                           throws OperationNotFoundException

Gets an operation type given its ID. Throws an exception if the operation is not found.

Throws:

                                  InvalidChainException

Builds the operation chain given a context. If the context input object or the chain cannot be resolved (no path can be found through all the operation in the chain) then InvalidChainException is thrown. The returned object can be used to run the chain.

Throws:

Exception

InvalidChainException

compileChain

                         OperationParameters... chain)

                                  InvalidChainException

Same as previous but takes an array of operation parameters

Throws:

Exception

InvalidChainException

run

Object run(OperationContext ctx,
         OperationChain chain)
           throws OperationException,
                  InvalidChainException,
                  Exception

Builds and runs the operation chain given a context. If the context input object or the chain cannot be resolved (no path can be found through all the operation in the chain) then InvalidChainException is thrown.

Throws:

OperationException

InvalidChainException

Exception

run

Object run(OperationContext ctx,
         String chainId)
           throws OperationException,
                  InvalidChainException,
                  Exception

Throws:

OperationException

InvalidChainException

Exception

run

Object run(OperationContext ctx,
         String id,
         Map<String,Object> params)
           throws OperationException,
