 +=== preserve_inlineDeclarationT(#​firstField,​ [#​otherField1,​ ...]) ===
 +
 +This fact is used for preserving the original appearance of the source code after transformations. It declares that multiple variables are declared in a single declaration,​ being written as
 +<Code lang-java>​int i, j, k; </​Code>​
 +instead of
 +<Code lang-java>​int i;
 + int j;
 + int k; </​Code>​
 +
 +== History ==
 +  * JTransformer 2.9: Added as inlineDeclarationT
 +  * JTransformer 4.0: Renamed to preserve_inlineDeclarationT
 +
 +=== Arguments ===
 +== ==
 +**#​firstField:​** [[fieldt|fieldT]],​ [[localt|localT]]\\ ​
 +ID of the first variable.
 +
 +**[#​otherField1,​ ...]:** [[fieldt|fieldT]],​ [[localt|localT]]\\ ​
 +list of IDs of other variables. These facts are marked with an [[omit_fieldt|omit_fieldT]] fact.
 +
 +=== Sample Java Source ===
