For each object created, a set of operations is available for +examining or changing its properties. + +Furthermore, complex data types, such as C structures, are represented +in a tree format. For instance, the @code{struct} type variable is the +root and the children will represent the struct members. If a child +is itself of a complex type, it will also have children of its own. +Appropriate language differences are handled for C, C@t{++} and Java. + +When returning the actual values of the objects, this facility allows +for the individual selection of the display format used in the result +creation. It can be chosen among: binary, decimal, hexadecimal, octal +and natural. Natural refers to a default format automatically +chosen based on the variable type (like decimal for an @code{int}, hex +for pointers, etc.). + +The following is the complete set of @sc{gdb/mi} operations defined to +access this functionality: + +@multitable @columnfractions .4 .6 +@item @strong{Operation} +@tab @strong{Description} + +@item @code{-var-create} +@tab create a variable object +@item @code{-var-delete} +@tab delete the variable object and its children +@item @code{-var-set-format} +@tab set the display format of this variable +@item @code{-var-show-format} +@tab show the display format of this variable +@item @code{-var-info-num-children} +@tab tells how many children this object has +@item @code{-var-list-children} +@tab return a list of the object's children +@item @code{-var-info-type} +@tab show the type of this variable object +@item @code{-var-info-expression} +@tab print what this variable object represents +@item @code{-var-show-attributes} +@tab is this variable editable? does it exist here? +@item @code{-var-evaluate-expression} +@tab get the value of this variable +@item @code{-var-assign} +@tab set the value of this variable +@item @code{-var-update} +@tab update the variable and its children +@end multitable + +In the next subsection we describe each operation in detail and suggest +how it can be used. + +@subheading Description And Use of Operations on Variable Objects + +@subheading The @code{-var-create} Command +@findex -var-create + +@subsubheading Synopsis + +@smallexample + -var-create @{@var{name} | "-"@} + @{@var{frame-addr} | "*"@} @var{expression} +@end smallexample + +This operation creates a variable object, which allows the monitoring of +a variable, the result of an expression, a memory cell or a CPU +register. + +The @var{name} parameter is the string by which the object can be +referenced.

This section -describes the @sc{gdb/mi} operations that will be available and gives some -hints about their use. - -@emph{Note}: In addition to the set of operations described here, we -expect the @sc{gui} implementation of a variable window to require, at -least, the following operations: - -@itemize @bullet -@item @code{-gdb-show} @code{output-radix} -@item @code{-stack-list-arguments} -@item @code{-stack-list-locals} -@item @code{-stack-select-frame} -@end itemize - -@subheading Introduction to Variable Objects in @sc{gdb/mi} - -@cindex variable objects in @sc{gdb/mi} -The basic idea behind variable objects is the creation of a named object -to represent a variable, an expression, a memory location or even a CPU -register. For each object created, a set of operations is available for -examining or changing its properties. - -Furthermore, complex data types, such as C structures, are represented -in a tree format. For instance, the @code{struct} type variable is the -root and the children will represent the struct members. If a child -is itself of a complex type, it will also have children of its own. -Appropriate language differences are handled for C, C@t{++} and Java. - -When returning the actual values of the objects, this facility allows -for the individual selection of the display format used in the result -creation. It can be chosen among: binary, decimal, hexadecimal, octal -and natural. Natural refers to a default format automatically -chosen based on the variable type (like decimal for an @code{int}, hex -for pointers, etc.). - -The following is the complete set of @sc{gdb/mi} operations defined to -access this functionality: - -@multitable @columnfractions .4 .6 -@item @strong{Operation} -@tab @strong{Description} - -@item @code{-var-create} -@tab create a variable object -@item @code{-var-delete} -@tab delete the variable object and its children -@item @code{-var-set-format} -@tab set the display format of this variable -@item @code{-var-show-format} -@tab show the display format of this variable -@item @code{-var-info-num-children} -@tab tells how many children this object has -@item @code{-var-list-children} -@tab return a list of the object's children -@item @code{-var-info-type} -@tab show the type of this variable object -@item @code{-var-info-expression} -@tab print what this variable object represents -@item @code{-var-show-attributes} -@tab is this variable editable? does it exist here? -@item @code{-var-evaluate-expression} -@tab get the value of this variable -@item @code{-var-assign} -@tab set the value of this variable -@item @code{-var-update} -@tab update the variable and its children -@end multitable - -In the next subsection we describe each operation in detail and suggest -how it can be used. - -@subheading Description And Use of Operations on Variable Objects - -@subheading The @code{-var-create} Command -@findex -var-create - -@subsubheading Synopsis - -@example - -var-create @{@var{name} | "-"@} - @{@var{frame-addr} | "*"@} @var{expression} -@end example - -This operation creates a variable object, which allows the monitoring of -a variable, the result of an expression, a memory cell or a CPU -register. - -The @var{name} parameter is the string by which the object can be -referenced.
