◆ AdvanceOffset()

void StringParameters::AdvanceOffset ( size_t  advance)
inline

Advance the offset within the string from where to return the next result of GetInt64 or GetInt32.

Parameters
advanceThe amount to advance the offset by.

Definition at line 72 of file strings_internal.h.

References parameters.

◆ GetDataLeft()

size_t StringParameters::GetDataLeft ( ) const
inline

Return the amount of elements which can still be read.

Definition at line 153 of file strings_internal.h.

References offset.

◆ GetNextParameter() [1/2]

uint64_t StringParameters::GetNextParameter ( )
inline

Get the next parameter from our parameters.

This updates the offset, so the next time this is called the next parameter will be read.

Returns
The next parameter's value.

◆ GetNextParameter() [2/2]

template<typename T >
T StringParameters::GetNextParameter ( )
inline

Get the next parameter from our parameters.

This updates the offset, so the next time this is called the next parameter will be read.

Template Parameters
TThe return type of the parameter.
Returns
The next parameter's value.

Definition at line 104 of file strings_internal.h.

References GetNextParameter().

◆ GetNextParameterReference()

const StringParameter & StringParameters::GetNextParameterReference ( )
protected

Get the next parameter from our parameters.

This updates the offset, so the next time this is called the next parameter will be read.

Returns
The next parameter.

◆ GetNextParameterString()

std::string_view StringParameters::GetNextParameterString ( )

◆ GetRemainingParameters() [1/2]

StringParameters StringParameters::GetRemainingParameters ( )
inline

Get a new instance of StringParameters that is a "range" into the remaining existing parameters.

Upon destruction the offset in the parent is not updated. However, calls to SetParam do update the parameters.

The returned StringParameters must not outlive this StringParameters.

Returns
A "range" of the string parameters.
