TypeMatcher() [1/4]

lldb_private::TypeMatcher::TypeMatcher ( )

delete

TypeMatcher() [2/4]

lldb_private::TypeMatcher::TypeMatcher ( ConstString  type_name )

inline

Creates a matcher that accepts any type with exactly the given type name.

Definition at line 79 of file FormattersContainer.h.

TypeMatcher() [3/4]

lldb_private::TypeMatcher::TypeMatcher ( RegularExpression  regex )

Definition at line 82 of file FormattersContainer.h.

TypeMatcher() [4/4]

lldb_private::TypeMatcher::TypeMatcher ( lldb::TypeNameSpecifierImplSP  type_specifier )

inline

Member Function Documentation

CreatedBySameMatchString()

bool lldb_private::TypeMatcher::CreatedBySameMatchString ( TypeMatcher  other ) const

inline

Returns true if this TypeMatcher and the given one were most created by the same match string.

The main purpose of this function is to find existing TypeMatcher instances by the user input that created them. This is necessary as LLDB allows referencing existing TypeMatchers in commands by the user input that originally created them: (lldb) type summary add –summary-string "A" -x TypeName (lldb) type summary delete TypeName

GetMatchString()

ConstString lldb_private::TypeMatcher::GetMatchString ( ) const

inline

Returns the underlying match string for this TypeMatcher.

Member Data Documentation

m_match_type

lldb::FormatterMatchType lldb_private::TypeMatcher::m_match_type

private

Indicates what kind of matching strategy should be used:

• eFormatterMatchExact: match the exact type name in m_name.
• eFormatterMatchRegex: match using the RegularExpression object m_type_name_regex instead.
• eFormatterMatchCallback: run the function in m_name to decide if a type matches or not.

m_name

ConstString lldb_private::TypeMatcher::m_name

private

Type name for exact match, or name of the python callback if m_match_type is eFormatterMatchCallback.
