Parameter Accessor Methods

The Value property of a Parameter object gets or sets the content of that object. The content is represented as a VARIANT, a type of object that can be assigned a value and any of several data types.

ADO/WFC implements the Value property with the getValue method, which returns a VARIANT object; and the setValue method, which takes a VARIANT as an argument. VARIANTs are highly efficient in certain languages, such as Microsoft Visual Basic. However, you can attain better performance in Microsoft Visual J++ by using native Java data types.

In addition to the Value property, ADO/WFC provides accessor methods that use Java data types to get and set the content of Parameter objects. Most of these methods have names of the form getDataType or setDataType.

There is one noteworthy exception: There is no getNull property; instead, there is an isNull property that returns a Boolean value indicating whether the field is null.

public boolean getBoolean()
public void setBoolean(boolean v)
public byte getByte()
public void setByte(byte v)
public double getDouble()
public void setDouble(double v)
public float getFloat()
public void setFloat(float v)
public int getInt()
public void setInt(int v)
public long getLong()
public void setLong(long v)
public short getShort()
public void setShort(short v)
public String getString()
public void setString(String v)
public boolean isNull()
public void setNull()
