Constructor Detail

WOSearchOperation

public WOSearchOperation(WOContext context)

Method Detail

invoke

public Object invoke()

Performs a search using an EOFetchSpecification based on the argument keys paths, and argument values.

Overrides:

invoke in class WOOperation

Returns:

NSArray of objects matching search arguments

fetchLimit

public int fetchLimit()

Returns the maximum number of objects to fetch for this operation. Subclasses should override this method to provide a custom fetch limit based on operation attributes or D2WContext information. The default implementation returns the D2WContext value for the key fetchLimit.

Returns:

the fetch limit to use in this operation's EOFetchSpecification

qualifier

public EOQualifier qualifier(EOEntity entity,
                             NSArray inputPartKeyPaths,
                             NSArray values,
                             NSArray comparisonKeys,
                             NSArray attributeClassNames,
                             String unspecifiedArgumentKey)

Returns a qualifier for searching on an entity. Subclasses should override this method to provide custom qualifiers based on operation attributes or d2wContext() information. The default implementation invokes WOServiceUtilities.buildQualifier()

Parameters:

entity - the EOEntity that will be the root entity for the qualifier to build

inputPartKeyPaths - array of property key paths

values - array of values corresponding to inputPartKeyPaths

comparisonKeys - array of key-comparison keys

attributeClassNames - array of Class objects

unspecifiedArgumentKey - String key representing a value that was not specified by the client

Returns:

a qualifier to use in this operation's EOFetchSpecification
