Attributes and Elements
Required. If this expression evaluates to true, the contents of this <case> element are executed. If false, this <case> is ignored.
Specify an expression that evaluates to the integer value 1 (if true) or 0 (if false).
Optional. Specifies the scripting language in which any expressions (within in this element) are written.
Can be "python", "objectscript", or "basic" (not documented). Default is the language specified in the containing <process> element.
Optional. <case> may contain zero or more of the following elements in any combination: <alert>, <assign>, <branch>, <break>, <call>, <code>, <continue>, <delay>, <empty>, <flow>, <foreach>, <if>, <label>, <milestone>, <reply>, <rule>, <scope>, <sequence>, <sql>, <switch>, <sync>, <throw>, <trace>, <transform>, <until>, <while>, <xpath>, or <xslt>.
Description
A <case> element is used within <switch>.
A <switch> element contains a sequence of one or more <case> elements and an optional <default> element.
When a <switch> element is executed, it evaluates each <case> condition in turn. These conditions are logical expressions in the scripting language of the containing <process> element. If any expression evaluates to the integer value 1 (true), then the contents of the corresponding <case> element are executed; otherwise, the expression for the next <case> element is evaluated.
If no <case> condition is true, the contents of the <default> element are executed.
As soon as one of <case> elements is executed, execution control leaves the surrounding <switch> statement. If no <case> condition matches, control leaves the <switch> after the <default> activity executes.
Activities within a <case> element can be any BPL activity, including <assign> elements as in the example below:
<switch name='Approved?'>
<case name='No PrimeRate' condition='context.PrimeRate=""'>
<assign name='Not Approved' property="response.IsApproved" value="0"/>
</case>
<case name='No Credit' condition='context.CreditRating=""'>
<assign name='Not Approved' property="response.IsApproved" value="0"/>
</case>
<default name='Approved' >
<assign name='Approved' property="response.IsApproved" value="1"/>
<assign name='InterestRate'
property="response.InterestRate"
value="context.PrimeRate+10+(99*(1-(context.CreditRating/100)))">
<annotation>
<![CDATA[Copy InterestRate into response object.]]>
</annotation>
</assign>
</default>
</switch>
