Class ParameterSet

java.lang.Object

com.progress.open4gl.dynamicapi.ParameterSet

public class ParameterSet
extends java.lang.Object

The ParameterSet holds the data for parameters for running a procedure, method, or function on an application server.

The ParameterSet is used is two phases: 1) Set ALL the parameters (INPUT, OUTPUT or INPUT_OUTPUT) 2) After the execution of the 4GL procedure - get the output values (don't get them if you don't want to. The object can be reused for another call. When setParameter() is called, the object is cleaned up, so the output from the previous call gets lost. The setParameter() calls are currently set to NOT check the validity of the data type and the input/output mode since the assumption is that our ProWrap tool rather than a user would use this interface. make a setParameter (... false) rather then setParameter (... true) calls if you want to change that. Marshaling and unmarshaling of parameters is done by describing a set of parameters as a relational table. That way, the same code the was implemented to marshal and unmarshal Temp-Tables into and from sql result sets can be used to marshal and unmarshal scalar data. The ParameterMetaData.java class (in this package), describes an input parameter value as the tuple: Unspecified value, int proType, int inOut_mode The data type of "value" is unspecified since unlike "real" relational data, not all the value of a parameter set have the same data type. The ParameterMetaData.java class (in this package), describes an output parameter value as the tuple: {int paramNum, int proType, Unspecified value) Note that output parameters don't need the inOut_mode descriptor but instead require the paramNum descriptor (since only OUTPUT and INPUT-OUTPUT parametrs are sent back), so ParameterMetaData and ParameterMetaData are not identical.

isDataGraph

public boolean isDataGraph(int position)

Determine if a parameter is to be represented as a data graph. Only datasets can be represented as data graphs. However, it is also possible for a dataset to be represented as an XML document or JSON string.

Parameters:

position - integer indicating which parameter in the list to test.

Returns:

a boolean indicating that the parameter is a dataset that is represented as a data graph.

getFlags

public int getFlags(int position)

Information specific to dataset serialized as XML. Includes flags from Memptr. Memptr.DSET_BI and Memptr.RPC_DSET.

Parameters:

position - 1-based parameter positionh.

Returns:

integer containing bit flags.

                  throws Open4GLException

Set the attributes of a parameter in the set. This is used by the Open Java Client. This overloading assumes the parameter will not be serialized XML.

Parameters:

p - integer identify the 0-based position of the parameter in the parameter list.

v - Object to be stored in the given parameter object as the parameter value.

m - integer indicating input, output or input-output mode (INPUT, OUTPUT or INPUT | OUTPUT).

proType - integer identifying ABL data type for the specified parameter.

isExtent - boolean indicaring whether this is a scaler value (false) or an extent (true).

extentValue - integer giving the length of the extent. Only valid if isExtent is true.

Throws:

Open4GLException - if m is an invalid value.

                  throws Open4GLException

Set the attributes of a parameter in the set. This is used by the Open Java Client.

Parameters:

p - integer identify the 0-based position of the parameter in the parameter list.

v - Object to be stored in the given parameter object as the parameter value.

m - integer indicating input, output or input-output mode (INPUT, OUTPUT or INPUT | OUTPUT).

proType - integer identifying ABL data type for the specified parameter.

isExtent - boolean indicating whether this is a scaler value (false) or an extent (true).

extentValue - integer giving the length of the extent. Only valid if isExtent is true.

serializeFormat - int indicating that the value stored in the parameter specified by p will be represented as an XML or JSON string.

isRpcStyleSoapMessage - boolean to be used to inform the AppServer that XML serialization will need to be modified RPC style messages.

writeBeforeImage - boolean indicating whether a before image should be included when the value is serialized as XML or JSON. This parameter is only meaningful if serializeFormat is 1.

Throws:

Open4GLException - if there are invalid parameters:

• m is an invalid value
• proType is neither Parameter.PRO_DATASET nor Parameter.PRO_DATASETHANDLE and isSerializedXml is true.
